BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent N0.'663,040, dated December 4, 1900. Application filed January 8, 1900. Serial No. 655. (No inodel.)

To all whom t may concern:

Beit known that I, DARIUs T. PHILLIPS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Bottle-Stoppers, of which the following is a specification.

My object is to provide a bottle-stopper of a simple, durable, and improved construction which may be opened, Without removal from thebottle, to permit ready pouring of the bottles contents and which when closed operates as an eifective stopper.

In carrying out my invention I provide a bottle having its neck portion formed With a plurality of preferably-inclined guide-grooves, with stops at their outer endsand shoulders at their inner or lower ends and a cylindrical cap having a closed outer end and an opening in its side and fitting over and turning upon the neck, the cap having inwardly-projecting shoulders movable in said guidegrooves, which operate when turned beneath the said shoulders on the bottle-neck to lock the cap in its closed position and engage the stops at the ends of the guide-grooves when the cap is opened to prevent its removal from the bottle.

In the drawings, Figures l and 2 are developed views of the cap and bottle-neck, respec-v tively, of the preferred form; Fig. 3, a broken side elevation of the bottle and cap with the cap closed; Fig. 4E, a similar view of the bottle Without the cap; Fig. 5, a sectional view showing the cap closed, and Fig. 6 a sectional View showing the cap opened.

A is the neck portion of a glass bottle, terminating in a head B, presenting an abrupt annular shoulder or plurality of lockingshoulders a, inclined or spirally-extending guide-grooves b, terminating in abrupt stops b', and a downwardly-extending lug or shoulder a at one side of each guide-groove.

C is a cylindrical metal cap closed at the end and fitting over the head B. In one side of the cap of the preferred construction is a pouring-opening c, which may be a series of perfor-ations or cuts of any desired shape, and the cap is milled or roughened circumferentially, as shown at CZ. In the cap, and preferably cemented thereto, is a bottle-mouthclosing stopper-piece e, which may be in the form of a disk or of any desired form and of cork or any other suitable material.

When the bottle is filled, the cap is placed thereon and pressed firmly down to impress the mouth of the bottle into the yielding surface of the disk e and cause the'latter to effectively close the mou th. A suitable instrument is then employed to-indent the cap and produce shoulders f on the inner surface thereof beneath the shouldered. The metal of which the cap is formed should be sufficiently flexible to permit its being bent 0r indented, as described, to produce the shoulders without danger of breaking. The engagement of the shouldersf with the shoulders a will hold the stopper tightly closed. To open the stopper, the cap is turned axially until the shouldersfstrike the stops a and register with the grooves b. The cap is then lifted until the shoulders f strike the stops b', the latter serving to confine the cap to movement in a vertical direction sufficient only to bring the pouring-opening above the bottlehead. The contents of the bottle may then be poured out through the pouring-opening c. In order that the stopper may be readily closed again, as when all the contents of the bottle are not poured out and it is desired to exclude the air, the end portions of the shoulders o. may be rounded off at the grooves b to produce cams 0.2, whereby in turning the cap the stopper will be tightened in place.

My improvement is particularly adapted to bottles Which are to be returned to the bottler when empty, because it offers a safeguard against the use of the bottles for other purposes and prevents the loss occasioned by removable stoppers. By employing a suitable instrument, Which may be inserted bet-Ween the neck and cap to iiatten out the shoulders f, the cap may be removed to permit washing and refilling of the bottle and the cap may be used over and over again.

Although I prefer'to construct my improvements throughout as shown and described, they may be variously modied without departing from the spirit of my invention as defined by the claim.

What I claim as new, and desire to secure by Letters Patent, is-

IOO

The combination of a bottle having a head formed eXteriorly with segmental lookingv shoulders and guide-grooves extending from carry its said indentations beyond the ends of the shoulders and into the guide grooves permitting it to be raised, the stops at the ends of the grooves confining the cap to movement in a vertical direction snioient only to bring the pouring-opening above the bottle-head.
